 forming a body of a door to include a transparent part, at least partly;    washing the transparent part; and    forming a first layer of a hydrophilic material on an inside surface of the transparent part.    
     
     
         12 . The method as claimed in  claim 11 , wherein the body and the transparent part are formed by injection molding of a plastic.  
     
     
         13 . The method as claimed in  claim 12 , wherein the body and the transparent part are formed of ABS resin or PC resin.  
     
     
         14 . The method as claimed in  claim 11 , wherein the step of washing includes the step of washing the transparent part with a wash liquid.  
     
     
         15 . The method as claimed in  claim 14 , further comprising the step of drying the transparent part for a predetermined time period after the step of washing.  
     
     
         16 . The method as claimed in  claim 11 , wherein the step of washing includes the step of blowing compressed air to the transparent part.  
     
     
         17 . The method as claimed in  claim 11 , wherein the step of forming a first layer includes the step of coating a liquid hydrophilic material on the transparent part.  
     
     
         18 . The method as claimed in  claim 17 , wherein the step of coating includes; 
 the step of spraying the hydrophilic material onto the transparent part, or    the step of dipping the transparent part into the hydrophilic material.    
     
     
         19 . The method as claimed in  claim 17 , further comprising the step of drying the transparent part after the step of coating.  
     
     
         20 . The method as claimed in  claim 19 , wherein the transparent part is dried in a room at a room temperature for at least 24 hours.  
     
     
         21 . The method as claimed in  claim 11 , wherein the step of forming a first layer includes the step of attaching a film of hydrophilic material to the transparent part.  
     
     
         22 . The method as claimed in  claim 11 , wherein the first layer is formed of cross-linked polyurethane.  
     
     
         23 . The method as claimed in  claim 11 , further comprising the step of forming a second layer of a high hardness material on an outside of the transparent part after the step of washing.  
     
     
         24 . The method as claimed in  claim 23 , wherein the step of forming a second layer includes the step of coating a liquid high hardness material on the transparent part.  
     
     
         25 . The method as claimed in  claim 24 , further comprising the step of drying the transparent part after the step of coating.
